Just achieved my high score of over 1B this past weekend, but I have yet to reach the final battle. What previous poster said was true: one game could be 600M followed by a 30M stinker. I seem to average around 300M like OP. Brutal machine; physics and placement of objects seem to generate lots of drains. As my only machine, I can say I never really get tired of playing it, but is that a function of being a great machine or me only having one?
